I'm pretty sure Superman Red was a very brief design. In the midst of his power overload, he briefly split off a red variant filled with more rage. It was interesting, and I'm surprised they never really revisited these over the years. There was a female blue at one point, but that's about it. You'd think they'd bring it back, and maybe add in a yellow one to complete the trifecta. Was I tempted to add a yellow? Yes. And a green. But I resisted.

Head, upper torso, arms, and upper legs were from Hyperion. Lower torso and lower legs were from Wonder Man. Heavily sanded down and resculpted the mask and hair on the head. From there, a full repaint, and all done!
